Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design specifications before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 2.0x1.6mm footprint matches your PCB layout constraints. Check if the standard XO performance meets your phase noise and stability needs for the intended application environment.

Oscillators Selection Notes

Select this component when a small form factor and low voltage operation are critical. The integrated power-down feature makes it suitable for battery-operated systems. Ensure the LVCMOS output level is compatible with the receiving digital logic. Consider the operating temperature range if the device will be used in extreme environmental conditions.

Oscillators Part Context

This part belongs to the 18QHTF series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies and package sizes. The 'PD' suffix indicates the inclusion of a power-down pin or function. This specific model provides a 24.55 MHz output, distinct from other variants like the 51.2 MHz or 8.0 MHz versions in the same family.

Oscillators Replacement Considerations

Direct substitutes include other 24.55 MHz LVCMOS oscillators in a 2.0x1.6mm SMD package with 1.8V operation. Verify pinout compatibility and electrical parameters such as current consumption and startup time. Cross-reference with similar models from Mercury Electronics or other manufacturers offering equivalent footprint and performance specifications.
